The City of Sammamish’s East Lake Sammamish Parkway Project is now underway, and drivers are advised to expect increased traffic delays throughout the spring and summer.

Although work will be allowed from 7 a.m. to 8 p.m., both lanes of the parkway will be kept open before 9 a.m., and between 5 and 6 p.m.

Substantial completion of the project is expected by late September.

Since the length of traffic delays is difficult to predict, drivers are advised to consider alternate routes.

The parkway project will reconfigure the intersection at Inglewood Hill Road and extend improvements north along the parkway for about four-tenths of a mile.

In addition to accommodating an increasing flow of traffic, it is hoped the project will also make safety and environmental improvements.

Construction of a roundabout in Issaquah at East Lake Sammamish Parkway and Southeast 43rd Way is expected to start in late spring or early summer. The city hopes the roundabout will improve traffic congestion and traffic safety at the intersection.

This project is also expected to cause traffic delays in north Issaquah.

More information on timing is expected in the coming months.
